Abstract (en)
In a contact-type vapor and particle sampling apparatus for collecting vapor or particles from a moving subject (14), a wand (16,16a,18,18a,20,20a) having a plurality of sampling holes (22) is oriented so that the holes extend in the direction of movement of the subject. The external width of the wand is less than a characteristic dimension of the contour of the surface of the subject being sampled, and a central fluid flow passage in the wand is sufficiently wide to prevent substantially all particles of on the order of about 10 microns in diameter from colliding with the wall of the wand as they enter the passage. A collector for use with the apparatus includes a gas impermeable material having a high binding affinity for explosives vapor exposed on a surface of a filter woven to trap explosives particles. <IMAGE>
